Improvement in the manufacture of artificial stone



grate/Lea To all whom it may concern:

Be it known that I, EDWARD WESTERMAYB', of St. Louis city and county, and State of Missouri, have invented a new and useful Im- 5' provement for the Manufacture of Artificial Stone, &c; and I do hereby declare the following to be a full, clear, and exactfiescription thereof, which will enable others skilled in the art to which my invention appertains II to make and use the same. I

' My invention consists in producing artificial stone, tiles, bricks, moldings, paving material, &c., of any desired form or color, by mixing and compounding certain materials, and subs jectin g the mixture to certain novel processes, hereinafter explained. I f" v In Letters Patent heretofore granted me by the United States Patent 0fi1ce,bearing date 7 October 12, 1869, for artificial stone, &c., I {'0 take one (1) part of Portland, or other ood I cement one-half g par 0 0 can san an mh) part of sla cinder oi iron, and mix together in a ry s a e; an or ridgepiers I take one (1) part cement, one (1) part ,5 sand, one (1) part slag, and six (6) parts of fine or coarse rav l and to these mixtures, separately, I Mater alone, or water containin g sulphate of iron or copperas in solution,

4 V :4]? in sufiicient-quantity to make a stifi mortar f g; by stirring up the mass thoroughly. At this V timeI and before molded, any desired color can Y 7;, be en the material by mixing any suitable pi 'ments with the mortar, such as India red, lamp-black, and other coloring material. This preparation I used for all the various articles heretofore mentioned, making only a distinction on stone for bridge-piers. When the mortar has been made I put it into molds of any desired form, and subject it to pressure by any suitable means, until compacted into a mass sufficiently firm, fixed,'and solid to form artificial stone, tile, bricks, moldings, bridge- 1 piers &c. The article so'fornied 1 then place 11? in a drying-room, and keep it there about two weeks, more or less, when I put it into a reservoir of clean water and allow it to remain about twenty-four hours, for the purpose of dissolving any particles of lime that may be adhering to or remaining in it, as "well as for increasing its hardness. After being removed 7 g found in the course of UNITED STATES PATENT OFFICE.

To give building-stone the color'of cement one-half poun me one-half 56TH (i) and mlxe wit ration of ingredients I use for'making building-stone and paving material. I then put the mortar into molds of any desired form for paving-stone or building-stone, therein to a pressure,

bridge-piers, paving material, &c. When the place it in a bath for about three be found .to possess'all the hardness bility of the best four or. fivejweeks to soap-stone, mixing these ingredients thor vat or box for that purwhich I dissolve one hundred (100) pounds of; r

n c it remain forty-eight (48)hours At the end of that time I drain ofi this water, and 1 In this way r} all fragments of coal an ot er impurities are 3 the sand. ""lo make building-stone, I take two (2) parts me t one (1) part avel two 2) parts san afififhree (3) PHII'tS (FI STE-g, (c inder 051 553- and one (1) part soap-gene. This I thoroughly ,1

mix in a dry sta e. terwardI take one-half (i) pound of orax for every ten (10) gallons of water, an m1x all the ingredients toa stifi I 1 water-glass. This is thoroughly stirred 1 e mortar} The above prepasufiiciently firm,j I fixed, and solid to form artificial stone, brick,

stone or other material heretofore mentioned is taken from the press, I place it in a drying-room for about five(5) days. I then hours, the bath being composed of ten (10) pats wate and one 1) part waterlass When a en from this ath, at the end of three hours, and [L allowed to dry for about twelve days, it will and duran qualities of natural stone, '5 and superior 'to it in many respects. I then I apply to the stone or other material, if de: 5 V sired, a coat of linseed-oil to prevent the 'action of water andfiost upon it. For making". tiles, generally I take two -(2) parts of sand,'. three (3) parts of cement, and one-half (2,) of

marble, I impregnate the mortar with the fol- I lowing: Ten (10) gallons water one 1) pound II 11 and subject it V I ong-hlyin a dry state. I then reduce this preparation to a thick mortar by adding one-half g) pound of borax to every ten gallons of water used, (dissolving the borax in the water first,) when it is ready-for molding. Any desired color can be given to the tiling or other material by mixing any suitable pigments with the mortar, as India red, lamp-black, and other coloring material.

I do not intend to confine myself to any specific proportion of the ingredients, as they may be varied indefinitely in the manufacture of various articles without departing from my improvement or invention.

The building-stone and paving material are susceptible of abeautifulpolish, which can be produced by finishing them with sand-paper. In this way I am able to produce or manufacture stone or other material to be employed in the different structures and for the difi'erent uses mentioned of any desired form or color. By cleaning the sand I not only add to the beauty of the stone or other material, but prepare it for the reception of the other ingredients, which have a more powerful effect, and produce a firmer and more durable article. By the additional ingredients I am able to manufacture a firmer stone, and at the same time produce a glassy and beautiful polish, if desired; also, to produce a paving-stone or material of any desired color, shape, or cast. By the additional ingredients and the cleansing-process, I am able to shorten the process of drying, and save time in the manufacture of the articles and materials.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Cleaning sand to be used in the manufacture of artificial stone, &c., by subjecting it to a bath of potash-wate r, as hereinbefore set forth. M

2. The manufacture of artificial stone, tile, 850., from a composition of matter consisting Witnesses:
